Abstract

The subject of the invention is a medium or high voltage circuit-breaker with self-arc blasting comprising a leakproof envelope filled with a dielectric gas and inside which are placed a first semi-fixed contact (4), electrically connected to a first current intake (2) and a second movable contact (7) electrically connected to a second current intake (5) and mechanically connected to an operating member, the said semi-fixed contact (4) being integral with a piston (8) moving in a cylinder (9), the said piston (8) delimiting in the said cylinder (9) a first volume (V1) on the arc zone side and a second volume (V2), the said semi-fixed contact (4) being subjected to the action of a spring (13) tending to displace the semi-fixed contact in the same direction as the moving contact during a disengagement operation, characterised in that the circuit-breaker comprises means of limiting, in the course of a disengagement operation, the speed and amplitude of the motion of the piston (8) in the direction opposed to that of the relaxing of the spring (13), the same means enabling unpolluted gas to be injected onto the zone of the arc contacts during the re-engagement operation following the said disengagement operation. <IMAGE>
